This paper investigates the nonlinear behavior of CRF filters. First, measurements carried out on stand-alone resonators underline the impact of resonator size and loading layer thickness on linearity. Then, a comparison between a BAW filter and a CRF filter is presented regarding second order nonlinearities. Finally, the nonlinear behavior of CRF filters at high power levels has been investigated through co-integration of the CRF with a silicon PA in order to evaluate its impact in a WCDMA application.
